 **Note that the midpoint of the PSIS markers is the same point as the SACRUM marker used for the Helen Hayes pelvis. Therefore, if a Helen Hayes markers set was used for the motion capture, a V3D_Composite pelvis can be created using the SACRUM marker twice (once for the left PSIS and once for the right PSIS).** **Note that the midpoint of the PSIS markers is the same point as the SACRUM marker used for the Helen Hayes pelvis.
